This past week we had a Porsche Cayman GT4 in for track prep. The Porsche Cayman GT4 is going to be attending the Carolinas Region PCA HPDE event we are hosting at CMP in Kershaw, SC. Below we will highlight a few points that should be inspected anytime before a Cayman GT4 hits the track. If you have any questions or concerns, please comment below or email us!
The Porsche Cayman GT4, along with any Porsche is known for being robust and durable. We do recommend a few things as with any mechanical component, proper maintenance is key! We recommend performing an oil change after two track day events. Oil is the life of the engine and performing an oil service is “cheap insurance” on your engine. After 6 track days, we recommend gearbox service. The gearbox oil goes through a very high heat abuse and will cause the fluid to break down prematurely compared to standard street use due to the high temperatures of track use. The air filters are prone to getting dirty very quickly and should be inspected after every track weekend. Due to the scoop design and air filter housing, the air filter ducts are prone to holding debris in the ducts and contaminating the filters much quicker then Porsche maintenance interval recommends.
The suspension components on the GT4 are world class. We recommend a visual inspection after every 2 track days to verify all components are in check. Rubber bushings can become fatigued and if the Porsche Cayman GT4 sees frequent track miles, its possible to see bushing wear and tear withing 10,000 miles of hard use. Also, check for loose joints and torn boots as well. If all the grease leaks out of a joint, it will surely fail at a much sooner interval. Generally, we recommend checking wheel bearings for play every inspection and replacement after 7000 track miles.
The brakes do very well on the Cayman GT4, but cross drilled rotors tend to heat crack. Keep an eye on the rotors and make sure none of the cracks reach the edge of the rotor. If the crack reaches the edge, you must replace the rotor or risk failure. Girodisc makes a great alternative to the stock rotor and by not having cross drilling, this will increase the life of the rotor. The stock pads are okay for mild track use, but we like the Pagid Yellow for track use while still allowing street driving. Keep an eye on camber wear on the tires to ensure you do not need to add more camber as your speed increases on the track. We prefer the Toyo R888R as alternative to the OEM tires and have had great success with all of our track cars utilizing the Toyos.
We hope this small bit of information will help with any questions on track prep for your Porsche Cayman GT4. This car is one of the best “bang for your buck” turn key track cars you can purchase. With just a few upgrades, the car is amazing on the track. If you are looking to upgrade your GT4 please give us a email or call, we have plenty of great upgrades to really optimize the car and improve street driving. Thank you for reading!
